This study compares minced carcass chemical composition and meat quality of castrated (CM), immunocastrated (IM) and entire male (EM), and female (FE) pigs at 70, 100 and 120 kg target body weights (TBW) (n = 80; 20 per sex). Sex affected fat, protein, and moisture content of the minced carcasses. Carcass fatty acid (FA) composition was affected by sex, with higher saturated and monounsaturated FA content in CM than in FE, IM and EM, and higher polyunsaturated FA in CM than in EM, with FE and IM in between. Except for intramuscular fat, which was higher in CM than in FE and EM, no significant differences between sexes were found in meat quality. TBW affected carcass chemical composition and some meat quality traits. An interaction between sex and TBW was found with IM approaching EM or CM depending on TBW.
本研究比较了去势公猪（CM）、免疫去势公猪（IM）、未去势公猪（EM）和母猪（FE）在目标体重70、100和120千克时（体重目标，TBW）的胴体切碎化学成分和肉质（n = 80；每个性别20头）。性别影响了切碎胴体的脂肪、蛋白质和水分含量。胴体脂肪酸（FA）组成受性别影响，CM中饱和脂肪酸和单不饱和脂肪酸含量高于FE、IM和EM，CM中多不饱和脂肪酸含量高于EM，FE和IM介于两者之间。除了CM的肌内脂肪高于FE和EM外，肉质方面未发现性别间的显著差异。体重目标影响胴体化学成分和一些肉质性状。发现性别和体重目标之间存在相互作用，IM根据体重目标接近EM或CM。
